| Abstract: | In order to make full use of the available bandwidth of DTV services to transmit the best-effort IP service, the issue of dynamic bandwidth allocation between DTV and IP services was discussed. A novel bandwidth allocation algorithm was given based on service hierarchy and perceptual quality assessment system. The related architectures and the formulas are also presented. |
